Looks like I'm not going to get any fruit from my nectarine tree due to peach leaf curl. Does anyone know of an organic way of treating it?

Found this, maybe it will help  - https://www.lovethegarden.com/uk-en/article/peach-leaf-curl?gclid=CjwKCAjwtJ2FBhAuEiwAIKu19iiJyc8fPZrwBG6Y5r2sHdmM7UYZgYe9vQzEXZKiyz072C0KIiaiaxoCaVQQAvD_BwE

Any chance of a pic ?


In meantime, have you inspected carefully for sucking insects on underside of leaves?

When we had a garden with a nectarine we used a copper sulphate spray. It really made a difference. The tree went from one rather sorry looking fruit to 8 or 9 in just a year.  But I think you have to do it just before the leaves open so that the fungus doesn't have a chance to infect the plant.

I did buy something that is permitted on organic land and must dig it out again. It's probably too late to cure it this year so I must make sure I'm ready next spring.

Not too late to prune out and burn (or put in the rubbish bin) though [member=23109]Mad Goatwoman of Madeley[/member]

After-thought [member=23109]Mad Goatwoman of Madeley[/member] :

As you will know, there are plenty of household (organic) products that can provide some or good defence against plant fungal (& viral) diseases and then there are some (organic) not so "household" products besides the 'approved' commercial offerings.  (Commercial 'approved' offerings have obviously gone through extensive trials, whereas the non-commercial offerings have not.) Whether any one of these would help (along with the recommended pruning) is unknown, but surely gotta be worth trying a spray solution from one or more of, if only to make the PLC spores have to work harder to infect your nectarine again.  In no particular order:

- Bicarb' of soda (not baking powder!)
- Calcium chloride or nitrate
- Cinnamon powder or oil
- Epsom salts (Now, I understand this contains a sulphur compound so it would, perhaps, be my 1st choice.)
- Garlic
- Chilli
- Milk (!) - any sort of milk.
- Mustard oil/greens (Latter steeped 50% in water.  Can't recall whether needs to be diluted afterwards, but I think so)
- Neem oil (added via a warmed partially diluted/emulsified starter mix to add to final spray mix)
- Potassium bicarbonate
- Urine (!)

Even a seaweed spray solution or worm-cast liquor might help in some way.

Spray recipes/recommended dilutions readily found ont' web.

Additions of vinegar, veg' oil and liquid soap (not detergent) might also be considered with latter two helping with adherence/penetration.

Hope it doesn't seem like I'm trying to teach Granny, but I'm a firm believer in trying everything when the alternative 'approved' chemicals might need much more careful/onerous handling precautions (for health reasons or even environmental reasons) although they might be considered to be 'organic'.

I'm a great believer in trying without chemicals so I am going to start at the top of the list as I do have some bicarb. Thank you.
